Improvement in jelly-tumblers



UNITED STATES PATENT OFFIoE.

WILLIAM DOYLE, OF BIRMINGHAM, PENNSYLVANIA.

i IMPRCVEMENT IN JELLV-TUMBLERS.

Specification forming part of Letters Patent No. 136,492, dated March 4,1873.

To all whom it may concern:

Be it known that I, WILLIAM DO YLE, of Pittsburg, Allegheny county,Pennsylvania, have invented certain Improvements in Jelly- Tumblers, ofwhich the following is a specilication, reference being made to theaccompanying drawing which constitutes a part of the same, in which-Figure lis a side elevation of the jelly glass or jar proper 5 and Fig.2 is a like view of the jelly-glass complete, when provided with itsmetallic cap.

My invention consists in providing a jelly glass or jar with a cap orcover of thin metal or other equivalent material, which may be securedto the jar by any suitable means to protect the contents duringtransportation or while on storage, and yet be capable of easy removalas well as of reuse.

Previous to my invention jelly-tnmblers were usually covered with cloth,paper, tinfoil, or other liexible material, tied over the edge of thevessel. These covers were inconvenient and difficult to apply, and,furthermore, were liable to be ruptured, to be destroyed by insects, orto be injuriously affected by atmospheric influences.

My invention remedies these various imperfections by providing thejelly-glass with a cover of sheet metal, or other equivalent material,which, while it can be easily secured upon the top of the vessel andeasily removed therefrom, will be sufficiently strong` to resistl injuryfrom ordinary accidents, and of a character to prevent theencroachmentsof insects and vermin.

The particular construction which I have adopted, as the simplest formof carrying out my invention, is shown in the drawing; the glass b beingmade tapering inside from the top to the bottom, in order to secure themore ready discharge of the contents of the vessel, and the cap a beingprovided with a plain flange, formed by turning down the edge at rightangles, or nearly so, with the body of the cap.

As the cap is made of a slightly-elastic metal, it can be secured inplace by simply pressing the ange down over the outside of the glass.

The outside of the glass may, if desired, be prepared for receiving theflange in the manner shown in Fig. l, or by forming a shoulder upon it,as shown in Fig. 2; but this construction, by means of which a nicer fitof the flange is secured, is by no means essential. Any mode of securingthe cap that will hold it on with suicient tightness to prevent itscoming 0E in ordinary handling, and yet permit of its being readilyremoved when it is desired to use the contents of the jar, may besubstituted for the frictional method, here shown, of securing thecover, Without departing from the main feature of my invention.

I am aware that metal caps have been used upon cylindrical boxes of tinand other metal, as well as upon fruit-jars having their smallerdiameter at the mouth; but I believe that I am the first to havecombined such a cap or cover with a jar of such configuration as topermit its contents, however sti' and firm they may be, to be readilydisengaged from the interior of the jar when the j ar is inverted. It isplain to see that the article of manufacture thus produced must be ofgreat utility for household and domestic purposes.

In the manufacture of my jelly-glass, in order to fit it for thereception of a cap of sheet metal or other equivalent material, I shouldordinarily furnish it to the market in the form in which it comes fromthe molds, Without subjecting it to the usual finishing operations thata-re applied to drinkin g-glasses. The application of the ordinaryfinishing process would tend to smooth and round the edge of the vessel,as well as to expand or contract its mouth, thereby seriouslyinterfering with the perfect fitting of the cap, which is made of a sizeexactly corresponding with the size ofthe molds in which the jar isformed.

What I claim as my invention is- 1. A jelly-glass adapted for thereception of a cover of sheet metal or other equivalent material,substantially as described.

2. As an article of manufacture, the combination of a jelly-jar and acover of sheet metal or other equivalent material.

3. The combination of a jelly -jar and a iianged cover fitting over themouth of the jar, substantially as described.

WILLIAM DOYLE.
